SPECIFICATION forming part of Letters Patent No. 518,637', dated April24, 1894.

Application filed September 25| 1893. Serial lilo. 486,490. (No model.)

To @ZZ whom t may concern,.-

Be it known that I, ARTHUR VANHOUWEL- ING, a citizen of the UnitedStates of America, residing at Olivet, in the county of Mahaska, Stateof Iowa, have invented an Improvement in Straw-Stackers, of which thefollowingisa specification.

My object is to produce asimple and durable staokerthat maybe raised orelevated relative to the thrasher in the ordinary manner and beautomatically oscillated as required to distribute .the straw in asemi-circle.

To this end my invention consists first, in plvotally mounting a carrierof the ordinary kind upon a frame extended from a thrashlng machine, andin the arrangement and combination upon said frameof means for movingthe carrier in the segment of the circle andfor automatically reversingthe said movement when it has reached the limit of its stroke in bothdirections.

My invention consists further in certain o ther details of construction,arrangement and combination of the parts as hereinafter set forth,pointed out in my claims and illustrated in the accompanying drawings,in which- Figure l is a top or plan view of a portion of the thrashingmachine, and also a portion of a stacker with parts broken away to showthe mechanism for operating the stacker. Fig. 2 is a side elevation ofthe same showing the carrier in position ready for transportation, indotted lines. Fig. 3 is a vertical transverse sectional View through theline X X of Fig. 2. Fig. /ls an enlarged detail View showing the devicefor reversing the motion of the stacker, and Fig. 5 is a detail viewshowing a modified form of mechanism for performing the same functions.

Referring to the accompanying drawings the reference letter A is used todesignate a thrashing machine which is of the ordinary construction.

A2 designates a carrier having endless belts A3 provided with crosspieces A4, arranged to travel ,thereupon and carry straw from the bottomof the stacker to its top. A shaft A5 at the bottom ofthe stacker isprovided with belt wheels A3 over which the belts A3 are passed, so thatwhen said shaft is rotated the cross pieces A4 will be moved in thecarrier.

that it may be capable of a movement in a` vertical plane relative tosaid frame.

O designates a frame extended rearwardly from the thrashing machine andhaving at its outer end a plate C2.

O3 designates a segmental sprocket wheel having a plate C4 formed on itslower end to engage the plate O2 to provide for the rotation of thesprocket wheel relative to the frame O.

G5 is a rod fixed to the sprocket wheel O3 and passed downwardlytherefrom and having a sprocket wheel fixed to its lower end for upurposes hereinafter explained. The aforesaid frame B is firmly fixed tothe double flange wheel O3 by means of bolts B2 so that the carrier andthe sprocket wheel O3 will also be rotated synchronously.

D designates a vertical shaft, mounted in suitable bearings inapproximately the central portion of the frame O and having fixedthereto a gear wheel B2 and a sprocket wheel D3, D4 being a chaingearing the sprocket wheels C3 and D3 together. This shaft D is arrangedto be driven by a worm gear F fixed to a shaft F2 that is extendedhorizontally and is provided with a beveled gear wheel F3 at its rearend.

H designates a shaft rotatably mounted in the rear portion of the frameO and adapted to be driven by means of a belt H2 connected With thethrashing machine mechanism.

H3 and H4 are beveled gear wheels loosely mounted upon the shaft H andboth normally in engagement with the bevel gear'wheel F3.

J designates a clutch device slidingly but non-rotatably mounted uponthe shaft H between the wheels H3 and H4. 'lhis clutch is connected withthe lever J2 that is pivoted to IOO K designates downwardly projectingpins fixed to the sprocket wheel C2 at opposite sides thereof to engagethe forward end of the lever J2 when the carrier is at either extreme ofits movements as required to throw the clutch device J in and out ofengagement with the N and N2 and bevel gears N6 and N7 for impartingmotion to the shaft A5 of the carrier.

In practical operation it will be seen that when the machine is startedthe shaft H will be rotated by the belt H2. This motion will betransmitted to the sprocket wheel C2 in such a manner as' to move thecarrier in the segment of a circle in the manner hereinbefore indicated.Then when one of the pins K contact with the forward end of the lever J2it will be obvious that the friction clutch J will be thrownintoengagement with the opposite one of the wheels H2 and H4 whereby themotio`n is reversed and the carrier again started to move in theopposite direction. This oscillating movement of the carrier is ofcourse continualduringthe operation of the machine.

I have provided the following means for carrying the carrier when themachine is being transported7 as follows: O designates a truck connectedwith the frame C by means of a tongue O2and P is a cross piece securedto a frame P2 that is fixed to the aforesaid truck and tongue and thecarrier is adapted to rest upon a cross piece P, its forward end beingconnected with the shaft A5 hereinbefore stated.

In the modified form of gearing shown in Fig. 5 the lever J2 isconnected with the shaft H so that when the lever is moved laterally,the shaft H will be moved longitudinally. R designates a bevel gearwheel fixed to the shaft F2, and R2 and R2 are bevel gear wheels fixedto the shaft H and adapted to be brought into engagement with the gearwheel R when the shaft H is moved longitudinally. In this instance themechanism for reversing the le- Ver is, of course, the same as beforeshown.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent of the United States therefor, 1s-

l. An improved automatically oscillating straw stacker comprising thefollowing elements to wit; a suitable frame adapted to be attached toathrashing machine, a segmental sprocket wheel rotatably mounted in theouter end of said frame, a frame mounted upon said sprocket, a carrierconnected with said frame and capable of a movement in a vertical planerelative thereto, means for voperating said carrier by power derivedfrom the thrashing machine, a vertical shaft also mounted in said framea sprocket wheel thereon, a chain gearing the said sprocket with theaforesaid segmental shaft, a worm gear in mesh therewith and xed to asuitable shaft, mechanism adapted to rotate said shaft in eitherdirection, two pins projecting from the said segmental sprocket, a leverfulcrumed to a suitable support and adapted to be-engaged by said pinsand means whereby a reversal of said lever operates the mechanism forreversing the aforesaid worm gear, and means for operating the devicefrom the thrashing machine,substantially as, and for the purposes,stated.

2. In combination with a thrashing machine, a carrier composed of theparts A2, A3, A4, A5 and A5, frame B having the shaft A5 mountedtherein, a frame C fixed to the thrashing machine, a plate C2 mounted inthe outer end of the frame C, a segmental gear Wheel C2 having a plateC4 at its under side to mate with the plate C2, means for fixing tli'eframe B to the top of said segmental sprocket C2, a shaft D rotatablymounted in the approximate central portion of the frame C, a gearwheelD2 fixed to said shaft, a sprocket wheel D2 also fixed to said shaft, achain D4 connecting the wheels C3 and D5, a worm F, a shaft F2 connectedtherewith, a

beveled gear F3 on the end of said shaft, al

shaft H adapted to be driven by power from the thrashing machine, thegear wheels H2 and H4 rotatably mounted on said shaft H, a clutch Jarranged to be placed in engagement with either of the wheels H2 and H4,a lever J2 pivoted in a suitable support, a fork J3 at the rear end ofsaid lever J2, springs J4 interposed upon the shaft I-I between the endsof the fork J2 and bar H5 connecting the said clutch J with the springsJ2 for the purposes stated, pins K downwardly projecting from thesegmental sprocket wheel C2 to engage the lever J2, as set forth, ashaft C5 extended vertically through the forward end of the frame C,-sprocket wheels N, N, iixed to the opposite ends thereof, a chain N4for connecting the lower sprocket wheel with the thrashing machine andthe gearing devices N5, N6 and N7' for driving the mechanism-of thecarrier, all arranged and combined, substantially in the manner setforth, and for the purposes stated.
